AVI is a container from the 1990s, and the DivX or Xvid video usually sitting inside it is why a camcorder tape rip or a decade old download will not play on a phone. Converting to MP4 swaps that aging codec for H.264 and leaves you a file modern devices treat as native. Old material often comes out smaller too, since compression has improved a great deal since AVI was fashionable.
Frequently asked questions
- My AVI plays with no sound on my phone, does converting fix that?
- Usually yes. These files often carry audio as AC3 or MP2, which mobile devices ignore, and the conversion re-encodes the soundtrack to AAC that everything supports.
- Will my old low resolution video look worse?
- Nothing is upscaled or sharpened, the frame size you had is the frame size you keep. A grainy 640 by 480 clip stays a grainy 640 by 480 clip, just in a wrapper that opens.
- What about the interlacing on captured tapes?
- Interlaced footage passes through as it is. Combing on fast motion came from the capture itself and needs a dedicated deinterlacing step, which this page does not do yet.
